What is sodium silicate powder? There are two kinds ofsodium silicate; Chemical formula Na2SiO3, molecular formula 122.00 is sodium metasilicate. Chemical formula Na4SiO4, molecular formula 184.04, is sodium orthosilicate. Sodium silicate is a colorless solid with a density of 2.4g/cm3 and a melting point of 1321K(1088℃). It is an organic binder. Solid sodium silicate is commonly known as sodium silicate in the south and natron in the north. An aqueous solution of water glass is commonly called water glass. Pure solid water glass is colorless transparent solid; The sodium silicate sold on the market contains some impurities and is light blue. Sodium orthosilicate is a very rare colorless crystal with a melting point of 1291K(1088℃). Sodium silicate solution is alkaline (slightly stronger than soda ash) by hydrolysis. Because it is a weak acid salt, in the presence of hydrochloric acid, sulfuric acid, nitric acid, carbon dioxide can be precipitated. During storage, carbon dioxide should be strictly prevented from entering, and frosted glass plugs should be used to prevent adhesion with rubber plugs. In industry, sodium carbonate and quartz are commonly eutected to form Na2CO3+SiO2→Na2SiO3+CO2↑. The product is usually a light blue-green color due to the presence of ferrite. Used as inorganic binder (can be mixed with talcum powder, etc.), soap filler and acid resistant concrete. After adding pigment, it can be used as exterior wall coating and poured in the foundation soil of ancient buildings to make the soil firm.
Use of sodium silicate powder 1. It is used in the construction industry to manufacture quick-drying cement, acid-resistant cement waterproof oil, soil curing agent, refractory materials, etc 2. It can produce silicon fertilizer in agriculture 3. In other fields, sodium silicate is mainly used as an adhesive for master paper, wood, welding rod, casting and refractory materials, filler for the soap industry, soil stabilizer, and waterproof rubber agent. It is also used for paper bleaching, mineral flotation, and synthetic detergent. It is a component of inorganic coatings and a raw material for silica gel, molecular sieve, precipitated silica, and other silicon series products.
Preparation of sodium silicate powder Sodium sulfate (also known as sodium sulfate, anhydrous mirabilite) method: raw materials include sodium sulfate (anhydrous mirabilite), carbon powder, and quartz sand. The production process is the same as the sodium carbonate method, but the difference is that the furnace adopts a negative pressure operation and draws air after the kiln.
Price of sodium silicate powder Sodium particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Sodium. A large amount of large amount will be lower. The Price of Sodium can be found on our company's official website.
